After serving with the Canadian Artillery, and becoming an ace with the Royal Flying Corps, American Jens Fredrick Larson settled into architecture. At age 28 he began work at Dartmouth. As his reputation grew, he would go on to work with myriad clients and more than thirty-five colleges and universities in America and elsewhere including Colby College, Bucknell College, Wake Forest University, the City University of Paris, the University of New Brunswick, and the Institute for Advanced Study, Princeton. This text explores the history of Larson and his career, with a look at his major projects, and the challenges faced late in his career when a nascent Modernism denigrated and misunderstood the meaning and value of the Georgian style.
